FAQ

What is a 16 mm O-ring cord used for?

It is used to manufacture large custom-sized O-rings and heavy-duty industrial sealing components.

Can the cord be joined into an O-ring?

Yes. The ends can be bonded with suitable adhesives or joined by vulcanization to create custom O-rings.

Is NBR resistant to hydraulic oil?

Yes. NBR offers excellent resistance to hydraulic fluids, mineral oils and lubricating greases.

Is this material suitable for outdoor use?

For long-term outdoor exposure, EPDM or VMQ silicone rubber generally provides better resistance to UV radiation and ozone than NBR.

Which industries commonly use this sealing cord?

It is widely used in hydraulic equipment, industrial machinery, agricultural machinery, heavy equipment maintenance, OEM manufacturing and industrial service operations.
